Chronobiology is the science that studies the natural rhythms of living organisms – from sleep cycles to cell activity - all governed by internal clocks and influenced by light. Your skin also follows a 24-hour rhythm with distinctive needs: during the day it enters its preventive phase, focusing on defense, protection, and skin longevity; at night it transitions into its regenerating phase, dedicated to correction, renewal, and repair.
At GEZEITEN, we translate this science into skincare by designing dedicated day and night rituals with programmed ingredient release and targeted marine actives that work in sync with each phase, restoring balance, resilience, and long-term skin health.
Skincare in sync with your
skin's natural rhythm
DAY
6 AM - 8 AM ∙ Skin Awakens
8 AM - 12 PM ∙ Defense Mode
2 PM - 3 PM ∙ Peak UV Stress
3 PM - 6 PM ∙ Energy Dip
NIGHT
10 PM - 12 AM ∙Repair Begins
12 AM - 2 AM ∙ Peak Repair
2 AM - 4 AM ∙ Detox Mode
4 AM - 6 AM ∙ Recovery Slows
Why Your Skin’s Rhythm Matters
When your skin’s natural rhythm is disrupted, it can no longer function properly: during the day it loses efficiency in defending itself, and at night it struggles to repair. This leads to reduced DNA repair, weakened barrier function, increased dryness and sensitivity, and accelerated signs of aging.
Balanced biorhythms are therefore essential for smooth, resilient, and youthful-looking skin.
our methodology
CHRONO-PHASE DAY 'PREVENTIVE ROUTINE'
Protecting your skin throughout the day against:
Blue light & digital aging
Photoaging & pigmentation
Environmental stress & free radicals
Collagen breakdown & loss of elasticity
Dehydration & transepidermal water loss
Stress-induced skin aging
OUR APPROACH Potent antioxidants, collagen-boosting peptides, and protective marine actives stabilise, strengthen, and shield your skin against daily aggressors. Prevention is the most effective form of anti-aging.
RESULT Resilient, balanced, and radiant skin.
CHRONO-PHASE NIGHT 'REGENERATIVE ROUTINE'
Supports correction & regeneration by:
Nourishing the microbiome
Activating cell recycling (autophagy)
Enhancing natural detox processes
Preventing moisture loss
Driving deep regeneration & structural repair
Accelerating cell renewal
Calming & repairing inflammation-related damage
OUR APPROACH Potent senolytics, retinol/retinal, peptides, and stimulating marine actives boost detox, regeneration, microcirculation, and cell recycling. Optimised for the skin’s nightly repair phase, they strengthen structure, accelerate renewal, and restore balance from within.
RESULT Smoother, firmer, visibly rejuvenated and rested skin by morning.
